I've written a RDBMS backed search engine that could do such queries, but it gets expensive after a while, as you have to do table-scans of the full text of every page in your DBMS to find the match. One thing I could have done would be to split up the match so it would try and match "perl and -V", before doing the full text search on the subset of results. Never got around to doing that though. I suspect most search engines (with the exception of maybe google) are in the same or similar boat.
